Taurus makes a good point. We only paid the big bucks for one night. We checked into the Poly NYE morning (around 11:00). The $500 bill was for that night only. We had to recheck in the next day because the price went WAY down the next day. (I had to specifically ask for this when I was making my reservations because, of course, CM's would not volunteer this information.) We had one set of reservations at the premium NYE rate and one set at a discount rate of something like $275 a night.
I didn't have any trouble getting into the building I wanted. There are a limited number of lagoon view buildings, I think. Specifying that I wanted that specific building made it pretty easy, though, of course, we will all tell you that with Disney nothing is a guarantee.
I didn't find the rooms to be at all run down. This was almost a year ago now, but still. From time to time, there seems to be a run of "the Poly is run down" posts on the board. I've stayed there twice in two different buildings and not found that to be the case either time. (Once I stayed there during a hurricane -- Hurricane Floyd. That was fun.)
This has been a very stressful year for my family. It seems that one thing after another keeps making it so, even for my nine-year-old. When I ask myself if it was worth the money we spent, I think about what he (my son) says. "Our New Years trip to Disney World was the most memorable trip we've had so far, Mom. I wish everyday would be like that." Indeed.
If money were at all an issue, I wouldn't think twice about staying at the Swan or the Dolphin. (We kind of prefer the Swan.) They are lovely. But for a special holiday, the Poly will definitely make the magic.
